So, I've been trying to track down a Wonder Card for the current UK Arceus and I found two from different sources. Both of them have all of their Wonder Card and Pokémon data exactly the same, apart from one which has the Corresponding Card number as 0, while the other is 1.
I was wondering whether this makes a difference or not, and if so; which is correct?

(My apologies if this is in the wrong forum, I'm still getting used to the place ^^; )
